2 CLEANING FOR BETTER OBSERVATION AND PHOTOMICROGRAPHY Microscope components get dirty with time. Dirt and dust particles on the optical components are especially damaging to image quality. When photographing important specimens which cannot be rephotographed, visible dust particles on the picture can be most frustrating. Therefore, we suggest the following critical microscope components be kept clean and dust-free. o Video Camera Wipe dust particles appearing on the monitor screen. If the particles move Photoeyepiece ~~."." only when the specimen or condenser Remove and clean, since dust particles is moved, clean the specimen and/or will be focused on the film plane. condenser. If the particle does not move when the eetv camera is rotated, clean the camera chip. Eyepieces Eyepieces get dirty frequently. Wipe carefully and gently so as not to damage the lens coating. Objectives Dirt and dust particles directly affect the microscope image. Wipe thoroughly and carefully with a cotton swab. 8)(50 Condenser Dirt and dust particles are easily seen. Always dust and wipe clean. Filter and light Exit Window Dust and dirt particles here have minimal effect on the image. However, the overall appearance requires frequent cleaning. Wipe evenly since this is a wide surface area. Built in Filters Difficult to clean. Please consult your Authorized Olympus Microscope Dealer. Mirror for large Format Attachment Dust and dirt particles here affect pictures. Difficult to clean without damaging the mirror surface, we advise you to contact your Authorized Olympus Microscope Dealer.

3 CLEANING TliE OPTICAL SYSTEM Although cleaning the objectives and eyepieces is relatively easy, here are some procedures and simple techniques to protect the lens coating and assure optimal performance. Required tools: Lens Tissue Cotton swabs (Q-tips) Blower Magnifier Cleaning Solution: 7 parts of ether and 3 parts of ethyl alcohol. The mixture ratio depends on room temperature and humidity. When the humidity is high, the ratio can be changed to 8 parts of ether and 2 parts of ethyl alcohol. Caution: Lightly brush the lens surfaces or blow with the blower before wiping with tissue. This removes particles that may scratch the lens surface. HOW TO CLEAN OBJECTIVE LENSES \, Wet the tip of a cotton swab with agenerous amount of lens cleaning solution. With acircular motion, wipe the front lens surface with the cot ton swab, to thoroughly remove any oil or dirt from the lens. Dip a new cotton swab in the cleaning solution and shake vigorously to remove any excess solution. Wipe the objective front lens from the center towards the periphery, while rotating the lens. HOW TO CLEAN TliE EYEPIECES Wrap a sheet of lens tissue around a cotton swab as illustrated. If the area to be cleaned is large, wrap the lens tissue looser and thicker. Otherwise, make a thin, tight wrap. Dip the wrapped lens tissue in the cleaning solution, and wipe the eyepieces from the center towards the periphery in a circular motion.

4 HOW TO CLEAN FILTERS Fold the lens tissue into two or three layers and soak it with cleaning solution as illustrated. Hold the filter at its edge, and wipe as you slowly rotate it. I ern HOW TO CLEAN THE PRISM Hold a piece of lens tissue between your middle and index fingers, then fold and wrap it around your index finger. Hold the tissue down with your thumb and soak it with suffi cient cleaning solution. Then wipe the prism surfaces clean, applying even pressure. IMPORTANT NOTES: Do not use the same lens tissue to clean more than one lens. Do not put an excessive amount of cleaning solution on the lens tissue. Blow on the surface of objects to be cleaned before wiping them.

5 MAINTENANCE USING ONLV A SCREWDRIVER EXCHANGING THE STAGE 1 2 Vertical For stage rack replacement, remove the stage from Remove the specimen holder and turn the stage Before disassembly, rotate the stage movement knob(s) the stand. upside down. to understand the construction and movement of the rack. 4 o I Replace the racks. In order to properly align the gear teeth, do not fu liy tighten the screws. Properly mesh the teeth of the racks and gear (see details on the following page). 6 Reattach the specimen holder to the stage. 7 Attach the stage to the microscope stand. To check that the rack adjustment is complete, observe a specimen with loox objective. The adjustment is complete if the specimen can be positioned smoothly, without play in the rack movement. Required items: c c Screw Driver Vertical Rack Horizontal Rack Screws

6 II ADJUSTING THE STAGE RACKS AND GEARS II After loosening the screw, gently push the edge Move the gear to the opposite end of the rack. Repeat the procedures of Steps 1 and 2, further of the vertical rack towards the gear. Then tighten Perform the same procedure as Step 1. tightening the screws. the screw nearest to the gear. After loosening the screw, gently push the edge Move the gear to the opposite end of the rack. Repeat the procedures of Steps 1 and 2, further of the horizontal rack towards the gear. Then Perform the same procedure as Step 1. tightening the screws. tighten the Screw nearest to the gear. The above procedures should be done until the racks are smoothly meshing with the gears along the entire length of the racks. See your Olympus Authorized Dealer for needed repairs or service.
